Having big problems at home where the stock is still plummeting Yahoo, finally, sells Kelkoo, the Paris-based shopping comparison search engine, according to Techcrunch.

Kelkoo was bought by Yahoo in 2004 for 475 million euros. Sadly enough, Yahoo couldn’t make it more profitable and known among other international shopping comparison search engines and thus Kelkoo usage has fallen down the hill (see the general trend record on Google Trends – the trends might vary for different Kelkoo domains).

Nothing new here, some of the acquisitions Yahoo made had the same fate…falling down to the competition.

The new acquirer of Kelkoo is Jamplant, a UK-based private equity firm (some details about this company here) and the amount they have paid is around 100 million euros.

Kelkoo will still continue to power Y! Shopping, Cars and Travel.
